Single Sign-on not working for some users

Hello Developer Community! I was referred here by Salesforce Support. I've had some users report that they are not able to login via SSO. I have validated that their Federation IDs are correct. Independently, they have worked with our internal tech desk and their usernames and passwords for SSO are correct (they are able to login to other applications with SSO). I have had them try logging in with both IE and Chrome and neither works. Any ideas as to why SSO is not playing nicely with SFDC? 

Many thanks,
Wendy

So only a few does not work? Others do work?

I suggest comparing the ones the worked with the ones that does not and see what differences are.

Things to lookout for:

1) The Federatation IDs (worth rechecking again comparing the good ones to the bad ones)
2) How are they SSO in?  A link? a desktop image? a favorite? etc. Check to ensure they all are using the same technique (same URL, link, etc.)

Thx
